It is basically 3 psi more than reading the Manifold MAP (So 22.4 psi for Manifold MAP, 25.4 psi for Boost Lo Res). This was addressed awhile ago. I just had to create a new Maths parameter since the data was already there.
It was explained that the ECU is hard coded to read the manifold MAP up to 22.4 psi even with the GMS1 tune and 3-bar MAP sensors. And yes if you looked at any of the screen shots I've posted, I'm running the GMS1 settings for everything. Doing a comparo with the Delta and Kappa GMS1 files, the sensor settings are the same.
For the DAL's, I'm going by what BYT posted in an earlier guide. I haven't found any newer guides that explained better settings for DAL. It seems everyone that tunes their LNF has a different opinion on how DAL correlates to boost. If you have a better idea, please do share.
Whatever the case, I think 25 psi is good enough unless someone out there objects or sees something blatantly out of place. I'm not out to push the envelope of my SS/TC, just trying to make it run a bit spicier than stock.
As for fuel pressure, I only mentioned it in the beginning because it was practically flat lined at the max with 25 psi of boost. As for desired vs actual, I just wanted to look at the actual fuel pressure. On the EcoBoost 3.5L V6, I was told that the direct injection high pressure fuel pump is the limiting factor. The engine and stock turbos can make more power, but the pump would run out of fuel and would be evident with low fuel pressure readings.
